This question seems so obvious I can't be the first to ask it, but searching this list didn't turn up anything.

How do I add an existing class to my class diagram? I have multiple class diagrams, one of which already contains a certain class. I'd like to add the same class to another diagram.

I've tried dragging the connection arrow from a class already in the diagram, choosing "Usage To", then choosing "Existing Element", but nothing happens. I've also tried opening up the .uml model and dragging the class I want over to the diagram, but nothing there either. I've also tried adding a shortcut from the diagram right-click menu, but this doesn't seem to be same thing (for example, it has a shortcut arrow).

Hi rodolphe,
Thanks for the info. I've tried this again with Eclipse v3.5.2 with the UML2Tools feature installed via Update Manager and I'm able to drag'n'drop to create shortcuts now. The "Create Shortcuts" menu item still doesn't do anything for me except mark the editor as dirty, but I'm fine with it.
